Thanx for the pix. 863 was the very machine!!
It ended up at Duxford after the AVPIN starter blew up on the first flight after Christmas leave. Took out not only some of the structure of the airframe, but a chunk of the tarmac too. Too expensive to repair, and it was the last one in service, so off to the museum.
Fortunately for those of us on D Sqn at the time, it was the boss who was flying it, so he couldn't blame us.
